From mboxrd@z Thu Jan 1 00:00:00 1970 From: Oleksandr Andrushchenko Subject: [PATCH v2] drm/xen-front: fix pointer casts Date: Wed, 23 May 2018 14:36:30 +0300 Message-ID: <20180523113630.29811-1-andr2000@gmail.com> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: xen-devel@lists.xenproject.org, linux-kernel@vger.kernel.org, dri-devel@lists.freedesktop.org, daniel.vetter@intel.com, jgross@suse.com, boris.ostrovsky@oracle.com Cc: andr2000@gmail.com, Oleksandr Andrushchenko List-Id: dri-devel@lists.freedesktop.org From: Oleksandr Andrushchenko Building for a 32-bit target results in warnings from casting between a 32-bit pointer and a 64-bit integer. Fix the warnings by casting those pointers to uintptr_t first.
